RUBBER HEEL.

To all whom 'it may concern: t

Be it known that I, SEYD HAvENs, a c1t1 l zen of the United States, residing at Oakland, in the county of Alameda and State. of California, have invented certain new and useful Improvements in Rubber Heels, of which the following is a specification,

reference being had therein to the accom-V panying drawing.

This invention relates to an improved heel for boots or shoes, and particularly to rubber heels that will at all times have a roughened or corrugated face or surface exposed to the walk, pavement, or other engagig-surfaces.

' other object of the invention is the production of a comparatively inexpensive heel that will prevent slipping, and at the same time will provide a yielding or springy effect when the boot or shoe, furnished with the same, is' in use.

With thesel and other objects in View, this invention consists of certain novel constructions, combinations, and arrangements of' parts, as will be hereinafter fully described .md claimed. i

In the drawin s: Figure 1 is a view in side elevr tion ao an improved heel vconstructed in accordance with my invention. Fig. 2 is an inverted plan view of the heel depicted in Fig. 1. Fig. 3 is a vertical sectional view taken on line 3 3, Fig. 2.

In carrying out the resent invention I construct the heel of alternating layersV or sections of hard rubber 1 and soft rubber 2; the layers or sections being, preferably, 'vulcanized together and arranged at an angle to a vertical plane, the angle or inclination being,A preferably, about forty-tive degrees. Each layer or section is provided at its outer end with a pair of beveled faces l5? whereby a sharpened or corrugated surface is formed upon the surface or pavementengaging face'of the heel. It is to be noted' that the hard rubber sections, layers or in-v sertions, do not detract from the-resiliency of the heel, because of the fact that the weight on the heel is applied at an angle to the longitudinal axis of the lavers or sections, which does not disturb tlie resiliency of the soft rubber insertions or sections 2,' but will still iin-rease the lift of the heel because of the stilfcning or reinforcing hard rubber sections or layers l.

Application led .Tune 19, 1909. Serial No. 503,198.

rIfhe soft rubber layers or sectionsr2 will be wornvl or chipped awa faster than the hard rubber layers 1, an therefore, there will always be a self-corru atiiw or sharpen- `ing act-iontaking lace w en the heel 1s in use, so that the eel will always have a sharpened or corru ated undersurface to prevent slipping 1as ong as any portion of p e boot or shoe.

gated or roughened outer surface is to .give an opportunity for foreign substances, coming in contact with the heel, (as is always the case with a heel) to wear away the soft rubber layers orsections more readily than if all of the outer layers or, faces of the sections 2 were flat, whereby a more eilcient structure is produced because ofthe roughened or corrugated rubber-face structure of the heel in its finished condition; hence, the importance of the double-face` or pointedstruct-ure of each section or layer.

It will be obvious that VI can attach my heel to any kind of afoot-covering, and, hence, I do not necessarily limit myself to a boot or shoe heel. Furthermore, it is .to be understood that the corrugated face is surrounded at the edges of the heel -by a Hat smooth surface l when the heel is constructed-see Fig. 2-the heel being provided with sharpened, corrugated or rou-ghened faces (when constructed) as shown in Fig. 2, for the feeding or self-sharpening action of the heel throughout lits ent-ire height or depth.

What I claimis:

l. As a new article of manufacture, a heel provided with alternatin hard and soft la-yers inclined in a vertica plane longitudinally of the shoe, and each layer provided at its surface-engaging end with. a beveled face.

2. As a new article of manufactule, a heel composed of inclined layers of hard and soft rubber, said layers being inclined longitudinally of the shoe in a vertical plane and each layer having its lower or outer edge formed straight and at right angles to the longitudinal axis of the layer.

In testimony whereof I hereunto affix my signature in presence ot' two witnesses.
